P: 4K H264 exports producing glitches and pixelation from media encoder Hardware Accelerated 2025

I've been dealing with files getting rejected from various clients from my 4K h264 exports.  I've tried different settings like rendering in Software Only CBR, etc..  It's a hit or miss for me.  Either way, I'm expecting more rejects to come.  No matter what I do with the 4K h264 settings, it's never consistent.   Now I have to use my old Imac to make these exports which is much slower but I'll deal with that until there's a resolve.  I would love to show you the images but they're adult related.  I can't post that here.  I've updated my Adobe apps and Mac OS to the latest update, hoping that will solve the issue.  That's not the case. 

 

Model Name: Mac Studio

   Chip: Apple M2 Ultra

  Total Number of Cores: 24 (16 performance and 8 efficiency)

  Memory: 64 GB

  System Firmware Version: 11881.81.4

Sequoia 15.3.1

 

Please look into this.

    Hi @alexandre_2086 - There is a potential fix in beta version 25.3.0 build 11 and higher.  Can you try it out and let us know if this fixes your issue.

    I would love to but I don't see that update available yet.  25.1 is the latest.

    Hi, when I export to H264 using hardware acceleration 1 VBR, the video during playback (Quicktime or preview on mac) is fine, but if I go back and forth with the cursor, for example to reach a certain scene, during this movement you can see some pixelated, square gliths.

    Attached is the example. Why? Before I didn't have the problem that occurred since I updated to MacOs Sequoia on a macbook pro 16" M3 Max.

    If I export without hardware acceleration, or in H265 (with hardware acceleration) I have no problems during the movement during playback.

    How do I solve it?

    Thanks.
